YBM3A-12/0.4 series box type substation

I want to make an inquiry
Product Description
The YBM3A-12/0.4 series prefabricated substation is designed and manufactured to meet the needs of domestic users. The utility model has the advantages of compact structure, strong set, safe and reliable operation, convenient maintenance, small appearance, small footprint and convenient movement. Product performance has reached the domestic advanced level.
◆The shell is designed according to foreign advanced technology and according to actual conditions. It has the characteristics of firmness, heat insulation and ventilation, dustproof, anti-small animal, moisture-proof, beautiful appearance and convenient maintenance. The shell material is available in aluminum alloy plate, steel plate and composite plate.
◆The high pressure side adopts compressed air type, SF6 load switch or vacuum load switch, which has reliable anti-misoperation function. The transformer can be either an oil-immersed transformer or a fully sealed transformer, and a dry-type transformer can be used. The low-pressure side adopts the latest plastic shell automatic air switch, which has high breaking capacity and good protection performance. The YBM3A-12/0.4 outlet circuit can be up to 30.
◆Automatic reactive power compensation device can also be selected when the user requests it.
◆The substation is equipped with a self-controlled exhaust device to meet the requirements of high temperature areas. Anti-condensation dehumidification heating automatic control device can be installed when the user requests it to meet the special requirements of the alpine region.
◆ The substation is easy to install, and the movable floor is installed in the low-voltage room of the substation. People can directly enter the cable trench.
◆ Substation has a variety of design options for use.
◆ On the basis of ordinary box-type substation, embed the main board, ceramic tile, etc. or other decorative materials according to user requirements. You can make a landscape box change.
